Whole-home filtration & conditioning
H2 ZERO Ultimate
The H2 ZERO Ultimate combines carbon filtration and salt-free conditioning in a system that needs no power, no drain connection and no regeneration cycle. It removes free chlorine and improves taste and clarity, while the HALO ION stage keeps hard-water minerals from forming scale.
Two technologies, nothing to plug in
The High Activity Carbon (HAC) media reduces free chlorine and taste-and-odour compounds across a wide pH range and is NSF/ANSI Standard 42 certified. Downstream, the HALO ION conditioner uses multi-reversing-polarity permanent magnetic fields to suspend calcium and magnesium so they wash through instead of coating pipes, and dissolves existing scale over time.
Because there is no backwash and no ion-exchange resin, the system draws no electricity, sends nothing to the drain and wastes no water.

Sizing
Two models cover most homes: one for 1-inch service lines and one for 1.25 to 1.5-inch lines. Milani sizes it to your line and peak demand so flow and pressure stay where they should.
- No salt, no electricity, no drain line
- Chlorine, taste and odour reduction
- Salt-free limescale control
- 10-year warranty on carbon and HALO ION
How Milani installs and looks after it
Milani installs HALO equipment on the main line where water enters the home (or, for drinking-water and point-of-use units, under the kitchen sink), tests your water first so the system is matched to what you actually have, and sets it up with the correct bypass and shut-offs so future service is simple. Where a unit has replaceable cartridges or media, we tell you the schedule and supply the parts.
